Improvement in photographic transfers

ORRIN P. HOWE, OF AUGUSTA, MAINE.

IMPROVEMENT IN PHOTOGRAPHIC TRANSFERS.

Specification forming part of Letters Patent No. 76,458, dated April 7, 1868.

To all whom it may concern:

Be it known that I, ORRIN P. HOWE, of Augusta, in the county of Kennebec and State of Maine, have invented a new and useful Improvement in Photographic Pictures; and I do hereby declare the following to be a full and exact description thereof.

My improvement relates to that class of pietures called ferrotypes, which are made upon enameled iron plates; and heretofore it has been customary, in finishing or putting up the ferrotype picture, to attach the plate containing the picture to the back of a card, with an aperture therein, showing the picture through the opening in the card. The objection to this manner of putting up the ferrotype picture is the stiff and cumbersome iron plate, which is exceedingly liable to become bent, defaced, scratched, and otherwise injured; to obviate which is the object of my invention, which consists in removing or transferring the j apanned or enameled coating from the iron plate by the aid of alcohol or chloroform, to-

left hand, and, with the thumb and forefinger of the right hand, proceed to bend back. and forth the upper right-hand corner of the plate until the enameled coating is separated from the iron plate sufficiently to obtain a hold with the thumb and forefinger of the left hand. I then drop a few drops of strong alcohol or chloroform between the plate and enamel at the point thus separated, and, by gently pulling the two surfaces in opposite directions, the enamel surface, with the collodion film and picture, is thus readily removed from the plate. The picture is then ready to be mounted upon the ordinary photographcard, in the style and manner of the card-photograph.

The advantages of my improvement are, the brief time required to produce pictures which ans wer all the purposes of the card-photo graphs on paper, at the same time retaining all the brilliancy and highly-enameled surface of the ferrotype. It also greatly increases the beauty and value of the picture by giving a fineness and permanency not heretofore attained by any other means.

I am aware of the previous use of alcohol and other substances for the purpose of trans ferring the collodion film from glass to paper by direct contact, and I do not, therefore, extend my claim to any such use; but

hat I claim as my invention, and desire to secure by Letters Patent, is-

Removing from the iron plate its japanned or enamel surface containing the picture, using for that purpose strong alcohol or chloroform, or any other article equivalent thereto, and mounting the same upon cards, inthe manner and for the purpose set forth.
